“…They suggest, rather, that the primary effect of the lesion is upon neural mechanisms related to food intake. DISCUSSION Previous investigations involving lesion and stimulation techniques have suggested that basal forebrain regions are involved in the neural control of feeding by the pigeon (Portmann & Stingelin, 1961 ;Phillips, 1964;Harwood & Vowles, 1966). The present study has localized the structures involved more precisely and shown that lesions in these structures produce disturbances in food and water intake.…”

“…This makes interpreting the effects of the Tn lesions more difficult. For example, there is a substantial literature dating back to the 1960s indicating that lesions to various parts of the archistriatum reduces fearfulness in birds [e.g., Phillips, 1964;Martin et al, 1979]. As mentioned previously, the study of Tn lesions in doves suggested that some of the effects on sexual behavior could be due to a reduction in fearfulness [Cheng et al, 1999].…”

Effects of Lesions of Nucleus taeniae on Appetitive and Consummatory Aspects of Male Sexual Behavior in Japanese Quail

et al. 2002

Neurochemical, hodological and functional criteria suggest that the nucleus taeniae and parts of the adjacent archistriatum represent the avian homologue of parts of the mammalian amygdaloid complex. It has been proposed in particular that the nucleus taeniae is the homologue of the mammalian medial amygdala. In male quail, relatively large lesions to the posterior/medial archistriatum selectively decrease the expression of appetitive sexual behavior in a manner reminiscent of similar manipulations involving the medial amygdala in mammals. We investigated the effects of discrete lesions restricted to nucleus taeniae and of lesions to an adjacent part of the archistriatum (pars intermedium ventralis, AIv) on the expression of appetitive (ASB) and consummatory (CSB) aspects of male sexual behavior. ASB was measured by a learned social proximity response (after copulation a male quail stands in front of a window providing visual access to a female) and by the frequency of rhythmic cloacal sphincter movements. CSB was assessed by the frequency of mount attempts (MA) and cloacal contact movements (CCM). Lesions confined to nucleus taeniae and to AIv did not influence the acquisition or the maintenance of the two responses indicative of ASB. In contrast, lesions of nucleus taeniae significantly increased the occurrence frequencies of MA and CCM when administered before the beginning of behavior testing and increased the frequency of MA only when performed on sexually experienced subjects. No effect of AIv lesions could be detected. The discrepancy between these results and previous experiments in quail might reflect procedural differences, but more probably differences in locations of the lesions that were restricted in the current study to the anterior part of taeniae. Those in the Thompson study were in the posterior part of this nucleus. These findings indicate that there is a larger degree of functional heterogeneity in the nucleus taeniae than previously thought. The effects of taeniae lesions suggest that this nucleus, similar to the medial amygdala in mammals, might be implicated in the control of sexual satiety.

“…Cortical and archistriatal lesions result in more pro found deficits in parrots [Phillips, 1968] than in pi geons [Akerman et al, 1962] or ducks [Phillips, 1964], and include leg weakness and slower recovery of loco motor function [Phillips, 1968].…”

In mammals, the supraspinal descending projections that influence distal limb muscles are the rubrospinal and corticospinal tracts. The former, which is found in other vertebrates, shows greater somatotopy in mammals that are 'dextrous' (e.g. monkeys) than those that are not (e.g. opossums). Similarly, the corticospinal tract, which is found only in mammals, has more extensive connections (i.e. direct corticomotoneural) in mammals that are dextrous than in mammals that are not. Descending spinal pathways have been described in 'non-dextrous’ avian species (chickens, ducks, geese and pigeons), and the purpose of this study was to determine if there are any differences in the origins of descending projections to the spinal cord in 'dextrous' or prehensile parrots (sulphur-crested cockatoo, Cacatua galerita, and eastern rosella, Platycerus eximius). True Blue or wheat germ agglutinin-horseradish peroxidase was injected into the lumbar or cervical spinal cord. The distribution of retrogradely labelled cells was similar to that previously reported for non-prehensile birds. We found no evidence of any direct spinal projections from the telencephalon (including any pathway homologous to the corticospinal tract of mammals), nor any specialized anatomical organization of the descending pathways that could account for the pedal dexterity of these species.
